Nest, makers of the massively popular learning thermostat, is getting into the smoke detector game with Protect. The Nest Protect is a sensor-packed smoke and carbon monoxide detector that aims to remove all the annoyances of the "modern" smoke detector, making it more helpful, more pleasing to use, and ultimately, safer. So, how does Nest aim to reach that goal?

Like the Nest Learning Thermostat, Protect is constantly connected to your Wi-Fi network. This allows you to set the device up with your iOS or Android device, and lets you use the Nest app to check things like battery life and other settings, while also receiving push notifications in the event of any emergencies. Even cooler, Nest devices can talk to each other. So, if the Protect senses a fire, it will let all the others know, and they will speak in a female voice alerting you to smoke detected in a particular room. If it senses a rise in carbon monoxide, it can let your Nest Thermostat know to switch off the heat.
